Answer:
A=8.75 in.
Step-by-step explanation:
Since ∆ HBA & ∆HKJ are similar,
HB/HA = HK/HJ
3/5.25 = 8/HJ
3HJ/5.25 = 8
3HJ = 42
HJ = 14 in.
AJ = 14 - 5.25
AJ = 8.75 in.
Therefore
A=8.75 in.
I hope this helped you.
Answer:

Step-by-step explanation:
This is a subtraction between polynomials, since both functions are polynomials, hence, to solve the problem with need to perform the subtraction, by coefficients.

By performing the subtraction, we have:

Answer: 18
Step-by-step explanation:
this is because complementary angles add up to 90 degrees so you would just subtract 72 from 90 to get your answer :)
The answer would have to be -4
